TV-B-Gone Kit 


Tired of all those LCD TVs everywhere? Want a break from advertisements while you're 
trying to eat? Want to zap screens from across the street? The TV-B-Gone kit is just what 
you need. With just a simple click of the button you can turn off any TV from 100's of feet 
away. Zap! 

Step 1 — Parts Check! 

• On the first slide for this guide, you will find a list of the supplied parts to build this kit. 

• Make sure you have all of the required parts. If you are missing any parts, check under 
your chair!

Step 2 — Insert the Tactile Switch 

• The tactile switch should be soldered into the S1 spot. 

• It does not matter which way you put it in. 

• Once it is flush with the board, turn it over and solder the connection. 

Step 3 — Brown-Black-Red Resistor 

5T 3r*» . 


• Insert one of the Brown-Black-Red Resistors into the R5 position. 

• It does not matter which way you put the resistor in. 

• Turn the board over and solder the leads.

Step 4 — Tips! 

• To make sure the leads stay in 
when you turn the board over, bend 
the leads outwards a little bit after 
inserting them into the PCB. 

• To ensure that there are no shorts, 
be sure to clip the leads of the 
resistors after they are soldered. 
Do this for all the components after 

Step 5 — Insert the Small Green LED at D5 

• LEDs have one longer lead and one 
shorter lead. The longer lead is the 
positive lead, and the shorter one 
is the negative lead. 

• Insert the longer lead into the hole 
marked with the (+) sign, and the 
shorter lead (-) goes into the other 
hole on the PCB. 

• Turn the board over, and solder the 
LED in.

Step 6 — Insert the Yellow Capacitor 

• The small yellow .1uF capacitor (marked 104) is to be inserted into C1. 

• This capacitor is not polarized, so it doesn't matter which direction you put it in. Push it 
through, bend the leads, and solder. 

Step 7 — Insert the Blue Ceramic Oscillator 

• The ceramic oscillator should be 
inserted into X1 on the circuit 

• The direction of insertion for this 
component doesn't matter. 

• Turn it over, and solder it in.

Step 8 — Insert the 8-PIN IC Socket 

• The 8-Pin Socket must be inserted into the PCB by matching the silkscreened 'notch' 
printed on the circuit board to the 'notch' on the socket. 

• Make sure the socket is flush with the board, turn it over and solder it in. 

Step 9 — Attaching the Battery Holder 

• Begin by trimming the leads on the battery holder until there is only about a quarter of the 
wire remaining. 

• Strip the ends of the wires so there is about about 1/4 " exposed. 

• The red wire is inserted into the positive (+) hole, the black wire is inserted into the 
negative (-) hole in the PCB. 

• Turn the board over and solder it in place. 

• To test, put the chip in the 8-Pin socket, add two AA batteries, and your LED light should 
be blinking. The chip should be inserted with the dot on the IC facing the notched end of 
the 8-Pin socket. Before moving on, remove the batteries from the holder.

Step 10 — Inserting the Next Resistor 

• In position R1, insert the other 
Brown- Black- Red Resistor. Like 
before, the orientation of the 
resistor on the PCB does not 

• Turn the board over and solder it 

Step 11 — Inserting the 220uF Capacitor 

• The blue capacitor has a longer lead, which is positive (+), and the shorter lead is the 
negative (-). 

• Insert this capacitor into C2, where the longer lead is inserted into the hole marked with a 


• Turn the board over, and solder the leads in.

Step 12 — Insert the first transistor. 

• The transistor marked 2907 should 
be inserted into Q5. 

• The flat end should be facing 
outward on the PCB, matching the 
silkscreen. Push the transistor 
through the hole, and solder the 
leads in. 

Step 13 — Inserting the 4 Transistors 

• Included in the kit are four NPN (2N2222) transistors. They are soldered into Q1, Q2, Q3 5 
and Q4. 

• Insert each transistor matching the silkscreen on the PCB. 

• Turn the board over, and solder the joints. Be sure to snip the leads to avoid anything 
shorting out.

Step 14 — Inserting the LEDs 

• Each IR LED has a longer lead and a smaller lead. The longer lead is the positive (+) 

• You will want the LEDs to face forward, so leave some room when you insert the LED into 
the PCB. (see pictures for LED orientation) 

• The two 'clear' LEDs go on the outside of the PCB, and the two 'blue' LEDs go on the inside 
as pictured. 

• After you solder the LEDs in, bend them forward. 

Step 15 — Finished!

• Now add two fresh AA batteries 
you're good to go! Keep in mind 
that the LED will blink continously if 
your batteries are low. 

• All done! Take this anywhere you 
need to zap a TV. Just point and 

• After hitting the button, the TV-B- 
Gone will continue to transmit for 
around 2 minutes, sending all the 
codes stored in the chip. 

• Enjoy!
